Abstract

The evolution of surface plasmon supermodes through the effective coupling of isolated surface plasmon modes in a semi-insulating quantum cascade laser (QCL) waveguide is thoroughly discussed here. The effect of varying the material and geometric parameters of GaSb/AlGaSb QCL operating at 3.0 THz are thoroughly studied using a full-vectorial finite element method.
